` Y16 claims.V A(o1. 70-47) This invention relates to the cylinder locks, and sleeve portion I4. and isi equipped with a flange more particularly to cylinder locks of the type I6 for cooperation With'a-slot' Ilof the sleeve I4 having a sleeve portion for-the Vaccommodation as seenin Fig'. 4. When it is` desired to secure f a key operated plug, and a driver containing thecylinder lock withinthe knob, it is merely portion for housing the spring pressed drivers necessary to first secure the sleeve portion I4 5 which eontrolthe rotation of the plug.Y e relatively to the knob. which maybe done by It has been customefyinthe manufacture of screw-threaded #means I8 as shown,` or by 'any Ylocking devices to' use `cylinder `looks to control other desirable means.
